COOLING DEVICE FOR SUPERCONDUCTING MOTOR

摘要

PURPOSE: A superconducting rotating machine cooling device using a heat pipe is provided to drastically reduce temperature deviation between a part close to a cold head and a part distant from the cold head by mounting the heat pipe at the winding part of a superconducting coil or a bobbin at which the superconducting coil is wound. CONSTITUTION: A shaft is inserted into the center of a center body for combining. A stator yoke(3) is combined at the outside of the center body. A superconducting coil is wound at a bobbin(4) mounted at the stator yoke. A cold head for cooling the superconducting coil is combined at the end of the shaft. A heat pipe(100) is mounted at one surface among the quadrant of the bobbin at witch the superconducting coil is wound or the winding part or the superconducting coil. Cool air transmitted through the cold head is rapidly transmitted to the entire bobbin through the heat pipe mounted at the winding part of the superconducting coil.
